How CNC Machining Works



The term CNC stands for 'computer numerical control', and the CNC machining definition is that it is a subtractive manufacturing process which typically employs computerized controls and machine tools to remove layers of material from a stock piece—known as the blank or workpiece—and produces a custom-designed part. This process is suitable for a wide range of materials, including metals, plastics, wood, glass, foam, and composites, and finds application in a variety of industries, such as large CNC machining and CNC machining aerospace parts.

The automated nature of CNC machining enables the production of high precision and high accuracy, simple parts and the cost-effectiveness when fulfilling one-off and medium-volume production runs. Before the operator runs the CNC program, they must prepare the CNC machine for operation. These preparations include affixing the workpiece directly into the machine, onto machinery spindles, or into machine vices or similar devices, and attaching the required tooling, such as drill bits and end mills, to the proper machine components. Once the machine is fully set up, the operator can run the CNC program.

The CNC program acts as instructions for the CNC machine; it submits machine commands dictating the tooling’s actions and movements to the machine’s integrated computer, which operates and manipulates the machine tooling. Initiating the program prompts the CNC machine to begin the CNC machining process, and the program guides the machine throughout the process as it executes the necessary machine operations to produce a custom-designed part or product.

CNC machining processes can be performed in-house—if the company invests in obtaining and maintaining their own CNC equipment—or outsourced to dedicated CNC machining service providers, like Amerascrew, Inc. in Mansfield, Ohio.

Although today is the era of the CNCs, not every job should be run on a CNC machine. Some jobs run faster and more efficiently in a conventional machine. Amerascrew's experienced engineers analyze your needs closely to give you the most cost-effective method for your parts. We have a vast array of secondary machines when needed. In many cases, a CNC does not have nearly the amount of cycle times as an automatic tapping, drilling, and threading machine or production mill.

When you are looking for a quality manufacturer of precision screw machine products, Amerascrew, Inc., is a name you can trust. Amerascrew is an ISO 9001:2015 registered company. We’re a hometown, third generation, family-owned business. We have built a solid reputation for quality and excellence with our absolute commitment to meeting clients' needs in the most cost-effective way.

Styles of Automatic Screw Machines

            When you hear the term "automatic screw machine" or the less formal saying of just "screw machine", you may be under the impression that they serve the same function as a screwdriver or drill. This is not the case. Automatic screw machines are essentially lathes used to machine parts for industry or sale. They are capable of threading material, although that is not their sole purpose.      A screw machine is essentially a lathe which rotates a piece of material (i.e., wood, clay, metal) on an axis to perform various operations such as cutting sanding, knurling, drilling deformation, facing or turning. At Amerascrew , our engineers analyze your needs closely to give you the most cost-effective method for your parts.     Automatic screw machines fall into two easily recognizable categories -- Swiss and Turret -- and while they function differently, their output and benefits are more or less the same.  ...

Plan your future with centerless grinding

  Why Centerless Grinding is Right For Your Projects You may have read one of our more recent articles about what precisely centerless grinding is. Still, you might not fully know the benefits of this type of machinery in comparison to its alternative: the age-old technique of centered grinding.  Centerless grinding has become increasingly popular today because of its efficiency. It is nearly 1.5 times faster than the more traditional method of the two types of grinding, saving a massive amount of time in production. This ensures that you’re receiving your product as quickly as possible. When working on a prompt deadline, centerless grinding is the best method to consider for your projects. Part of the reason centerless grinding is efficient is that it doesn’t require the same unloading process. In addition to being a time-saving method for creating round products, it is also relatively more straightforward and results in a less complicated process. Ultimately, this leave...
